SOUTH WICK WIRE FILLING CUTTER FOR WIRE FABRIC LOOMS Filed March 5, 1921 6 Sheetsf-Sheet' 6 tLJLL `beam 3, and an upper beam 4 connected at either end by upright-s 5. 6 represents the usual reeds for wire looms carried by cross beams 3, 4. Referring to Figures 14, and 15, the upper beam 4 of the lay is shown in top plan outline. In this type of loom the shuttle is carried by a bar supported by the lay. 8 is a conventional representation of a spool for carrying the wire filling which in practice is arranged in and carried by the shuttle. In this figure, 9 represents conventionally, but not as to structure or location, a spool tension carried by the Ispool holder for the wire filling. 10 represents a bracket conneet-ed with the framework of the machine provided with a. guide 11 over which the free end of the filling passes to 'a weight 110, 'see Figure 16, or other end tension device. The

supports and operating mechanisms for Aa lay, shuttle, etc. are not shown, forming no part of the present invention.

Referring to AFigures 1 to 13, 12 represents an oscillating shaft. This shaft at either end is mounted in a bearing 12a formed at the upper end of the casting 12b secured by -scr'ews 12c to opposite ends of the girt 2, only the right hand bearing appearing in the drawings. This shaft is operated by mechanism, not shown, whose time of operation is controlled by a filling feeler forming no part of this invent-ion. 13, Figure 13, represents a collar secured to the shaft 12 by a set screw 14. 15 represents a coiled spring on the shaft 12, one end being secured to the collar 13, the other end being secured to bearing 12'a in a common manner. The purpose of the 'spring 15 is to yieldingly resist the oscillation of the shaft 12 by the instrumentalities heretofore described and to return said shaftl 12 to its initial position.

16 represents Va lever, one end of which is secured to the shaft 12 by a set screw 17 see Figure 13 represents an arm on said lever 16 provided on its lower side and near its rear end with a lug 1-9. 20 represents a swinging bunter .pivoted at its top end on a stud 21 'carried by thc rear vend of the lever 18. The upper end of the bunter is formed as a finger or tail piece 22 adapted by engagement with the lug 19 to limit the motion of the bunter in `the direction of the hands of 'a watch, in Figure 6. The lower end of the bunter 2O is formed with a buffer meniber As shown in Figure 13, the lever 16 is at. the right of the bearing 12a. Upon the shaft 12 and to the left of the collar 13 is rigidly secured a gear segment 24 by means of a spl-it "boss .having ears 25, 25, held together upon the shaft 12 by a set screw 26,

see Figure 4. Upon the free end of the gear segment 24 are formed two gear teeth 27, 27. represents a Vcasting secured upon the girt 2, see-*Figure 2, and formed with a forwardly projecting arm 30 carrying at its upper end a. perforated boss 31. Referring to Figures 2 and 4, there is a bell crank lever comprising arms and 36, and this lever at its angle or elbow carries a boss arranged on the stud 34. The outer end of one arm 35 of this bell crank lever 'is arranged between the gear teeth 27, 27, while the outer end of the other arm 36 of this bell crank lever is arranged between the gea-r teeth. 38, 38 of the gear segment 39, that at its end is formed with a boss 40 loosely mounted upon a shaft 41. The shaft 41 in turn is arranged in a bearing 42 carried by an arm 43 pioje'cting from the casting 29. Upon the left hand `end of the shaft 41, see Figure 12, is mounted an adju-stable collar 44 adapted to be secured any desired position upon the shaft 41 by a pin 45 in fthe usual way. 46 represent-s a coiled spring mounted on the. shaft 41, the left hand end `of this spring being arra'ngiged in the collar 44, 'the right hand Aend of the spring 46 being secured inthe boss 42. The purpose of the spring 46 is to yieldingly resist Ythe 'motion'o-f the shaft, in Figure 2, in a direction opposite to the motion of the hands of a watch and, when the power is released, to turn thesh'aft in the 'direction of the hands of a watch until it returns to its original position. 41'a represents a bearing, see 'Fignre 12, for the right hand end of the shaft 41, said 'bearing Aextending from a plate 41b secured to the framework -by lag screws 41C. 47 represents a boss rarranged upon the'shaft 41 and rigidly secured thereto by Vmeans of a set screw 4Q.. This boss is formed with an arm 49 carrying vat its end a laterally proj-ectin g finger -50 arranged 'over the arm39 of the segment. see Figures 2, 4 and 12.

Referring to Figures 2, 4 yand 12, when the shaft 12 is operated as heretofore described, lsuch movement of the 'shaft will be opposite to the lia-nds of a watch. This movement is through a small'are. yAssuming the par-ts to bein the posi-tion shown in Figure 2` which is the normal and inoperative position, ysuch movement will throw the teeth 27, 27 to the right, lifting the arm 36 and the teeth 3S', 38 and rocking the yshaft 41 vin the direction opposite the movement of the Ahands of a watch. This Will carry-the parts to the position lshown in Figure 4, lifting the linger 50 and rocking the yshaft 41 against the. tension of the spring 46. When the power heretofore referred to is released from the sha-ft 12, the spring 46 through the action of .ft-he lever 49 'and the finger 50 and the gear segment 39 will rock "the shaft 41 in the direction of the movement of the hands of a watch and return the part-s to fthe position shown in Figure 2. 51 #represents fa. pint-le carried by a casting 52 secured at its lower vend to vthe girt 2, see Figure 7, the top of the casting being broken away vin Figure. Upon the pintle 51 loosely arranged a boss 53, see Figure 12, from the upper side of `which projects l. ll)

an arm 54, seeFigure-s 5 and 13, formed on;`

its rear face with two locking notches 55, 56 and above the notch 5 5 with `the idler recess 57. Upon the pintle 51 isV arranged a coiled spring 58,'see Figures 5, 12l and 13. 1 One end of this coiled spring is secured in` the arm 54. The opposite end of said spring is secured in a lockingy nut. 59,'iwhich is.

secured by a pin 60 to the pintle 51 in any desired position of adjustment bypassing the pin through corresponding holes in the locking nut 59and the pintle 51.

the arm 54 yieldingly to the left in Figure 1.

Upon the shaft 41, see Figures 7 and 8, is Y adjustably secured a split boss 61, they ears of which are clamped onthe shaft by a cap,

on the shaft 41 and spline 77 and its armk 63 thus clamped in any desired positioncorresponding to any selectedwidth of fabric' being woven and at a ldistance from rthe edge of the selvage lof the rfabric vat which it is desired to have the filling cut.- This is an important advantagesince. it does not interfere with the use`4 of the loom for the production of any desired width of fabric within the capacity of the loom, but further admits of positioningthecutter carried by said arm at the desired distance fromV the l edge of the selvage for eachk fabric. EX-k tending outward and upward from the boss 61 is an arm 63, which terminates'in an angular extension y64, the upper face ofwhich is formed to hold astationary cuttingblade 65.

68, see Figures 7 and 8. A spring 69, ar-y ranged on the shank of the screw 68 between the head of the latter andr theface of the movable cutter jaw 67, serves to mainf tain the two cutting blades 65 and r70 in proper contact with each other. 70 represents a steel Acutting blade secured in any desired way to the movable cutting aw 67, see Figure 11. 71 represents afinger depending from the inovablejaw and integral therewith. In the front facekof this finger and in the boss on the arm v63 are formed sockets 7 2, 73. 74 represents a coiled spring having one end arranged in the socket 73 and the other arranged inthe ksocket 72. This spring normally tends t'o keep the finger 71 to the left, see Figure 7, andthe movable jaw with its cutting blade 70 in a raised or inoperative position. y shaft near the bossy 61 is secured ,af boss 75 by means of a set screw 76 andd a vspline 77,V

Bythis arrangement the spring .58" tends tothrow 67 represents a 1 movable cutting jaw pivoted to the fixedfcutting j aw bya screw Upon the ing dogprojectngfrom the boss kand E adapted for engagement 'with' the locking' notches 55, 56 of thelever 54.

Assuming the partsto be in the position shownl yin Figure 1, when the shaft 12 is turned through a short arc upon the operation of the feeler, as heretoforedescribed,

kby reason ofthe connection between the shaft 12 and the shaft 41, lever 63 with its cutter is swung to the position shown in `Figure y3, at the same time the locking dog 78 is moved in a directionopposite to the movement 'of the hands of awatch from the notch y56 to the notch 55.

Y In ythe loom vas organized the feeler is upon the left side of the loom while the cutter, the cutter mechanism and magazine e are situated upon the right hand side of the loom.y As the shaft 12 is operated due to the timing ofthe` feeler, the shuttle 100, seeupper half of Figure 15, iwould be` upon the left. At this, time, that is at the commencement of the operation yof the shaft 12,` the cutter parts would be in the positionv shown in Figuresl and 2. The

. shuttle would then move to the right to the position shown in Figure 14, with the filling thread 80 `of ythey spent spool ypositively located'between the selvage and the 'shuttle in a predetermined f position due toA the action` of the spool tension 9 and the grip of the warp or Vselvage. This operation of the shaft 12 takesplace rwhile the lay is takingfitsreverse motion to the rear. The shaft 12 shownl in Figures 1 and 2 is operated at this time in a direction opposite f tov that of the hands of fa watch, Vand by means of the gear segment 24, bell. crank f arms 35 and `36v and the 'gear segment 39 turnsA the shaft 41 also in a direction oppositeto that of the hands of a watch,

throwing the'cutter fromy the position shown in Figure 1 to the position shown in Figure 3, ysee Figure 4-for the rposition of the gear segment 24 and other connecting parts at this time. `The operation of the shaft 41 further turns up the arm 78 sufficiently kso that it can engaged by thenotch 55 ofthe lever 54, the face 55 is brought down into engagement with ar1n'78 by means of the spring 58,` the parts assuming the position shown in Figure `3 and withthat part -of the fillingf80 extending from the shuttle to the selvage ina predetermined position x or plane, due to the co-action of the spool F tension and the selvage, between the open `jaws of the cutter. Asthe'lay returns to 16 are moved `from kthe position shown in Figure 5 to the `position shown in Figures 1 and 6, with the buffer member '293 engaging the upper end of the arrn I54C.

As the lay makes its lr'et'urn vstrokel to -beat up the first shot of the filling 'out of thereplenished spool, that part of the filling extending from the Seli/age to the Weight 110 and herein designated I81 has been like- Wise positively positioned due to the coaction of' the end tension 110 and the selvage between the ja'ivs of the Vcutter and the lay, engaging the finge r 71, Operates the movable cutter blade 70, severing the lling '81, see Figure 5, and just at the end of its stroke, the lay "engages the bunter 20, raising 'the ylever 521 and permitting the spring 456 on the 'sliaft 41 to turn vsaid 'shaft in 'the direction of the hands 'of a -Watch, thus bringing the arm 78 dovn into the notch 56, `V`or the original `position as `shown in Figure 1, and

likewise returning the cutter to V"the position diagrammatically, a receptacle or inagazi-n'e 101 'for a series of charged filling spools 8 arranged 'one over the other. By hand or by automatic means, the exhausted iilling `spool 8 is ejected from the shuttle and a charged 'spool inserted in the shuttle Wlienthe Jnarts are positioned as in Figure 14. The 'details of this magazine `-101 and the mechanism for shifting the 'spools oit filling are lnot shown because forming vno part of the present invention and `fbeing the subject of another application, the position ofthe magazine and 'its charged spools 8 being indicated in 'order to 'explain the position 'of parts at the time of the operation of the cutter. i

Referring to Figure 16, the Weight 110 attached 'to the end of each illing acts with the spool tension to keep the free vend of the filling from kinking and to 'keep .it in a predetermined plane 'until the iii-ling "has been caught bythe Warp, said Weightorend tension ltliereaiiter acting with the iv'arp 'or salvage to hold the said free 'end of the filling in a lpredetermined plane `-in position to be engaged bythe cutter at any desired kpoint adjacent the ys'e'lvage. tension 9, indicated Vin Figures 15 and 16, and the Weight 110 or `end tension Vlocated under the guide 11 in Figures 121 and 15, and shown in `side 'elevation yin Figure 16,

The spool are ea'ch fully show-n anddescribed in my application, Serial No. 179,677, patented July 18, 1922, No. 1,422,897 of which this application is a continuation in part. The action of the spool tension 9 against the end tension or Weight 110, as already stated, keeps the free end Iof the filling under control and vin `la predetermined position until the filling is caught 'by the Warp, While the spool tension y9, acting with the Warp, places and holds the un'vvoven end of the filling in a predetermined plane or position, engaga'ble 'by the filling cutter at any desired point adjacent the selvage. The adjustability of the Ecutter arm 65, see Figure 12, together with 'the predetermined orv fixed planes in which the filling is placed and held prior to and at 'the cutting operation, permits the rauto'r'natic 'cutting of the end oi 'the iilling at the Iedge of the selvage or at any v"desired point remote therefrom Within the range of vthe adjustment of the arm 65.
